Patent DE-3406114-A1 (DE)
Title: Device for exchanging valve inserts in heating systems and the like
Inventor: BEER ERICH
IPC: B25B27/24
Filed: 1984-02-21
Abstract: The device according to the invention serves to exchange defective valve inserts, or valve inserts blocked by welding beads or other causes, of hot-water central-heating systems or the like during full operation of the system, that is, without emptying beforehand. After the valve insert (3) is unscrewed from the valve housing (2) by turning the handle (8) on the shaft (9), the valve insert (3) is pulled out to the stop by pulling on the handle (8) and then the ball valve (4) is closed via a valve lever (9). Figure 2 shows this position. Water-pressure compensation between chamber (10) and discharge passage (11) is provided by unscrewing the shaft bearing (5). However, the entire water contents in the chamber (10) still cannot flow off on account of the lack of pressure balance. Only by further unscrewing of the shaft bearing (5) can the necessary pressure balance be effected via the connection (now additionally obtained) between air-inlet opening (12) and chamber (10), and the water in the chamber (10) can flow off. By further unscrewing of the shaft bearing (5), the valve insert (3) can now be removed and replaced by another. The exchanged valve insert (3) is inserted into the valve housing (2) in the reverse sequence. <IMAGE>

Title: Winding device without a traversing triangle
Inventor: LENK ERICH DR ING DR
IPC: B65H54/28
Filed: 1984-02-23
Abstract: The winding device according to the invention is to guide the yarn in the traversing zone so as to be free of transverse forces. For this purpose, it proceeds from a state of the art, in which the yarn is guided by two endless bands which form the traversing zone, extend in the direction of the winding bobbin on both sides of the yarn to be wound, diverge towards the said winding bobbin and are equipped with yarn guides. According to the invention, the yarn guides of the two bands are offset relative to one another in such a way that the yarn guide of one band is located at the yarn reception and that of the other band is at the same time located at the yarn transfer. In one version, each band possesses, offset relative to those of the other band, two yarn guides having a small spacing 2A = L-2l, A being the small spacing, L the extended band length and l the spacing between the yarn reception and yarn transfer. In another version, the extended length of each band is three times the spacing between the yarn reception and the yarn transfer. Each band has three yarn guides having an equal spacing between them. They are arranged mirror-symmetrically on the bands. Placed in front of this version is a transfer device which ensures regular changing from one band to the other.

Title: Method for generating an audible ringing signal
Inventor: GUENTER WILLI DIPL ING
IPC: H04M19/04
Filed: 1984-07-21
Abstract: A device for generating a ringing signal comprising a plurality of consecutive frequencies in the subscriber terminal device of a telephone switching system has four registers, the pulse/phase ratio being generated by the first register, the duration of the individual frequencies by the second register and the frequencies of the ringing signal itself by the third register. The fourth register serves to define the respective frequency. The first, second and third registers are connected to a clock generator which supplies increment pulses. These increment pulses serve to modify the data words present in the registers, an enable or disable signal being generated for the following register once a predefined value has been attained. The predefined values are freely selectable, whereby any ringing signal intervals and frequencies can be generated. The electro-acoustic transducer is activated by the third register.

Title: Circuit for indicating the intention to brake
IPC: B60Q1/44
Filed: 1984-08-16
Abstract: The essential part of the invention is the constructional arrangement and vehicle-dependent attachment of the microswitch A, the position of rest of the throttle linkage C closing the make contact G and the working position of the throttle linkage c closing the normally closed contact H. In this arrangement, it is completely irrelevant from which point of the throttle linkage C/c the control lever E/e is actuated. The invention described has the advantage of triggering, by the installation of a microswitch at a suitable point in the motor vehicle, light signals which indicate the intention to brake to drivers of motor vehicles behind. The driver of the motor vehicle behind now has the possibility of reacting much earlier than before to a braking process of the driver of a motor vehicle in front. He is thus prepared earlier for the braking process and, as a result, can avoid accidents. <IMAGE>

Title: Sealing arrangement subjected to pressure
Inventor: BELART JUAN
IPC: F16J15/3232
Filed: 1984-11-28
Abstract: The sealing arrangement (1) subjected to pressure, for a piston-cylinder arrangement, has a sealing ring (2) secured in a radial groove (24). On the sealing surfaces (9, 10) there is a further radial groove (3), which serves to accommodate a slip ring (4) which divides the sealing surfaces (9, 10) into two sections. Prior to installation of the sealing arrangement (1), the diameter (D1) of the sliding sealing surface (7) of the slip ring (4) is greater than the diameter (D2) of the sliding sealing surfaces (9, 10) of the sealing ring (2) which are arranged on both sides of the slip ring (4). When the sealing arrangement (1) is installed, the sliding sealing surfaces (7, 9 and 10) of the sealing ring (2) and of the slip ring (4) are brought to rest against the piston and cylinder walls (20). By virtue of these dimensions, it is primarily the elastic sealing ring (2) which provides sealing in the low-pressure range, generating low friction forces, while, in the high-pressure range, it is the slip ring (4), which slides more easily, which provides sealing, the said slip ring giving rise to only small friction forces compared to the sealing ring (2) due to its good sliding properties. <IMAGE>
